The client Danieli Environment is the division of Danieli specialized in the environmental protection offering proprietary technologies for water treatment, air pollution control, energy saving and more.The final user is ABS Acciaierie, a still mill plant located in the north of Italy. With the increasing cost of energythe client was looking for ways to improve the energy efficiency of the final user as well as reducing the impact on the environment of the plant. 

EXERGY's solution  was the installation of the ORC system for waste heat recovery with EXERGY's Radail Outflow Turbine. The ORC technology is applied to the electric arc furnace (EAF) and, by exploiting the hot waste gas generated by the steel mill, it produces 1 MWe. The heat from the waste gas is extracted using an intermediate fluid which then vaporizes the organic fluid in the ORC abstorbing the energy, before passing the turbine. Here it expands, causing the turbine to spin and creates electricity at the generator. By installing EXERGY's EPSd Radial Outflow Turbine, the client was able to recover the maximum amount of energy, thus increasing the electrical efficiency of the installation.

The ABS plant now produces electricity with zero extra emission saving 4.692 tons of CO2 and 1.499 tons of oil equivalent per year
